1 Claim.

the handle extending along the sash, it is necessary, when arriving at the corner to twist the the wrist of the hand holding the putty knife outward, so that the corner of the blade is at substantially 45 to the lower end of the sash, and this twisting movement often upsets the putty and it is therefore necessary to use several additional strokes to smooth off the putty at the corners; whereas with the end of the blade cut away at the sides, it is still possible to draw the knife downward with the same movement, and when it arrives at the corner it is already in position, so that it is only necessary to draw it outward to finish the corner.

The object of this invention is therefore to provide an improved putty knife, by which the corners of sash are readily finished.

Another object is to provide an improved glazing knife by which the edge of putty may readily be trimmed.

A further object is to provide a putty knife with which old putty may readily be removed.

And a still further object is to provide a pointed putty knife with trimming means thereon 35 which is of a simple and economical construction.

With these ends in view the invention embodies a relatively wide tapering blade, the thickness of which also tapers to a relatively thin edge at the outer end, and in which the corners are cut away, providing two sloping sides forming an angle of slightly less than 90, and one side is cut away at the point of intersection thereof, with the side of the blade forming a trimming notch.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein: 50

Figure l is a view showing a side elevation of the knife.

Figure 2 is a view looking toward one edge of the knife.

ure 1, showing an alternate design inwhich the trimming notch is omitted.

Figure 4 shows a knife with a relatively short blade. y

In the drawing the knife is shown as it may be made wherein numeral I indicates the blade, numeral 2, the handle, and numeral 3, the trimming notch.

The blade I, may-be of any suitable length or width, and the outer end is formed with a point 4, the sides of which slope toward the edges of the blade, and at the intersection of one side with the edge of the blade is an inwardly sloping edge 5, and at right angles thereto an outwardly sloping edge 6, which form the notch 3. This notch is formed so that the line 5, is substantially perpendicular to the handle so that it may be drawn down the edge of the sash to trim or remove old putty with the handle sloping slightly outward, thereby providing an easy movement of the knife, and at the same time a positive grip, so that force may be applied to remove old putty as desired.

The blade may be. secured in the handle 2, in any'manner or by any means, however in the design shown the blade extends continuously through the handle, and is secured thereto by a central rivet I, and smaller rivets 8 and 9. The handle may also be of any shape or design.

It will be understood that changes may be made in the construction and design of the knife without departing from the spirit of the invention. One of which changes may be in the exact shape or arrangement of the point at the end of the knife, another may be in the position of the trimming notch, or inthe use of additional notches, and still another may be in the use of ,a blade of any other shape in cross section.

The construction will be readily understood from the foregoing description. In use the knife may be held in one hand and with putty fed along the side of the sash with the other, the knife may be turned downward with one of the sloping sides of the point resting against the glass and with the angle as shown and described the putty will be applied so that it fills the corner with the outer surface sloping at the usual angle, and then as the knife. arrives at the corner it is only necessary to draw it straight outward from the position in which it has been held to form the corner. The knife may then be drawn down the side of the sash with the point at the end of the notch extending inward to trim Figure 3 is a view similar to that shown in Figthe edge of the putty if desired, or by holding the knife at a different angle this point may extend inward to remove old putty.

Having thus fully described the invention what I claim as new and desire to secure by Letters Patent is:

A glazing knife comprising a handle with a blade extending outward from the end of the handle with the edges of the blade sloping outward from the end of the handle for a portion of the length of said blade and then sloping inwardly for the remainder of the length of the blade to form a point at the end of the blade located in a line extending through the center of the handle, said inwardly sloping edges intersecting at the point at an angle of slightly less than ninety degrees.
